Den foreliggende opfindelse angår et rullestel for på paller lastet gods, og af den i indledningen til krav 1 angivne art.The present invention relates to a roller frame for pallet-loaded goods and of the kind specified in the preamble of claim 1.
Gods, der på paller skal opbevares i et gennemgangsreolsla-5 geranlæg, anbringes normalt på et rulleunderstel. Herved kan pallerne rulle fra indgangssiden til et reolfag, ved udgangssiden, og dette kan ske ved egen kraft ved en hældning i reolen eller ved samvirkning med transportorganer.Goods to be stored on pallets in a crawler storage facility are usually placed on a roller frame. In this way, the pallets can roll from the entrance side to a shelf compartment, at the exit side, and this can be done by its own power by a slope in the shelf or by interaction with transport means.
Når en lastet palle sammen med understellet tages ud af 10 reolfaget og stilles til side, kan det vare nødvendigt at flytte, omplacere eller på anden måde forskyde dette. Drejer det sig om kortere strækninger, er det oftest ikke nødvendigt at anvende mekaniske hjælpemidler. På den anden side vejer en lastet palle relativt meget, op imod 1.000 kg.When a loaded pallet along with the chassis is taken out of the shelf compartment and set aside, it may be necessary to move, reposition or otherwise displace this. In the case of shorter distances, it is usually not necessary to use mechanical aids. On the other hand, a loaded pallet weighs relatively much, up to 1,000 kg.
15 så at en person kun med stor anstrengelse kan flytte et lastet understel retliniet. Når et rulleunderstel imidlertid ikke er forsynet med styrbare ruller, er en bevægelse langs en krum bane alene med muskelkraft helt udelukket uden yderligere hjælpemidler.15 so that a person with great effort can move a loaded chassis straight. However, when a roller frame is not provided with controllable rollers, movement along a curved path alone with muscle power is completely ruled out without additional aids.
20 Til dette formål, dvs. for manuel manøvrering af tungt lastede rulleunderstel, er det tidligere foreslået at anvende såkaldte løftestangsruller. Disse består hovedsageligt af en lang og en kort løftearm, som sidder i en vinkel i forhold til hinanden, omkring et forbindelsespunkt, hvor der 25 er indrettet et rullepar. Med den kortere løftearm kan rulleunderstellet gribes fra neden og løftes lidt på, så dette relativt nemt kan skydes ud langs en kurve.For this purpose, viz. For manual maneuvering of heavily loaded roller frames, it has been suggested previously to use so-called lever rollers. These consist mainly of a long and a short lifting arm, which is at an angle to each other, around a connection point where a roller pair is arranged. With the shorter lifting arm, the roller chassis can be gripped from below and lifted slightly so that it can be pushed out relatively easily along a curve.
Disse kendte løftestangsruller er derimod helt utilstrækkelige, så snart gulvpladsen omkring rulleunderstellet er rin-30 ge, da det i såfald ikke er muligt at gribe understellet nedefra, ligesom vægtstangsforholdet kan være så ufordelagtigt, at en tung palle simpelthen ikke kan flyttes. En yderligere ulempe er, at et løftet rulleunderstel til tider u-frivilligt glider af løftestangsrullen, hvilket kan føre til 143648 2 forskydning eller endog medføre, at lasten falder af. Desuden indebærer disse indretninger en ikke uvæsentlig risiko for ulykkestilfælde, da de er ustabile, dvs. en sluppet løftearm reagerer hurtigt, og desuden i uanvendt tilstand i 5 høj grad har tendens til at vælte.These known lever rolls, on the other hand, are completely insufficient as soon as the floor space around the roller frame is low, as in this case it is not possible to grip the base from below, just as the lever ratio can be so disadvantageous that a heavy pallet simply cannot be moved. A further disadvantage is that a lifted roller chassis sometimes involuntarily slides off the lever roll, which can lead to displacement or even cause the load to drop. Furthermore, these devices pose a not insignificant risk of accident, as they are unstable, ie. an escaped lifting arm responds quickly, and in addition, in the unused condition to a high degree tends to overturn.
Opfindelsen har til formål at eliminere ovenstående ulemper, og tilvejebringe et rullestel for på paller lastet gods, hvilket rullestel er særlig hensigtsmæssig til brug, hvor der er ringe gulvråderum. Rullestellet ifølge opfindelsen 10 er ejendommelig ved, at mindst een rammeside af rulleunderstellet danner et omvendt U-profil med ulige lange sidestykker, hvoraf det korteste sidestykke vender udefter, og at trækstangen udviser et i hovedsagen med kvadratiske tværsnit udformet koblingsstykke, som er forsynet med et spor til op-15 tagelse af profilets kortere sidedel og som er svingbart lejret omkring en vinkelret på omdrejningsaksen for traskstangsrullerne forløbende aksel, hvilket koblingsstykkes tværsnit tilnærmelsesvis kan udfylde tværsnittet af det nævnte U-profil. Herved opnås på enkel måde mulighed for 20 etablering af en stabil forbindelse mellem traskstangen og rulleunderstellet, og det tilmed selvom trækstangens koblingsstykke forbindes sideværts ret vilkårligt med rulleunderstellets rammeside, hvilket gør det muligt at få fat i rulleunderstellet, selvom dets rammeside kun er delvis 25 frit tilgængeligt.The invention has for its object to eliminate the above disadvantages and to provide a pallet rack for palletized goods, which is particularly suitable for use where there is little floor space. The roller frame according to the invention 10 is characterized in that at least one frame side of the roller base forms an inverted U-profile with odd long side pieces, the shortest side of which faces outwards, and that the drawbar exhibits a coupler generally formed in square cross section, which is provided with a grooves for accommodating the shorter side portion of the profile and which are pivotally mounted about a perpendicular axis of the axis of rotation of the thrust bar rollers extending shaft, which the cross-section of the coupling piece can approximately fill the cross-section of said U-profile. This provides for a simple way of establishing a stable connection between the drawbar and the roller frame, and even if the coupling piece of the drawbar is laterally connected arbitrarily to the frame side of the roller frame, which makes it possible to grasp the roller frame even if its frame side is only partially free. available.
Jfr. krav 2 kan det kortere sidestykke af U-profilerne være tilsluttet bundstykket under en vinkel mindre end 90°, fortrinsvis 70-80°, hvorved opnås særlig nem tilkobling af traskstangens koblingsstykke, ligesom koblingen får en vis 30 selvholdende effekt. Denne effekt forøges ved, at de længere sidestykker af U-profilerne jfr. krav 3 har en indefter i U-profilet rettet forlængelse, hvorimod koblingsstykkets side modsat sporet kan ligge an. Krav 4 angiver en enkel, billig og robust udformning af trækstangen samt en særlig 35 hensigtsmæssig anbringelse af henholdsvis manøvreløftestang 3 143648 og akseltap for koblingsstykket. For at sikre en problemfri manøvrering af rulletrækstangen er nævnte spor jfr. krav 5 udformet ved koblingsstykkets øvre imod manøvreløftestangen vendende kantområder, idet koblingsstykkets 5 svingningsakse eller rettere dens forlængelse går igennem koblingssporet. Ved det i krav 6 angivne opnås på enkel måde en hensigtsmæssig udformning af koblingsstykket, idet den angivne affasning eller skråflade muliggør, at rulletrækstangen uden videre kan stilles til side på stabil må-10 de støttende på nævnte skråflade og i vel afbalanceret stilling.Cf.. Claim 2, the shorter side portion of the U-profiles may be connected to the base at an angle less than 90 °, preferably 70-80 °, whereby particularly easy connection of the coupling rod coupling piece is obtained, and the coupling has a certain self-sustaining effect. This effect is increased by the longer side sections of the U-profiles, cf. Claim 3 has an extension in the U-profile directed extension, whereas the side of the coupling piece opposite the groove can abut. Claim 4 specifies a simple, inexpensive and robust design of the drawbar as well as a particularly suitable positioning of the maneuvering lever 3 and the shaft pin for the coupling piece respectively. In order to ensure a smooth maneuvering of the roller draw bar, said track cf. Claim 5 formed at the upper regions of the coupling piece towards the maneuvering lever rod, the axis of oscillation of the coupling piece 5 or, rather, its extension passing through the coupling groove. In accordance with the claim 6, a convenient design of the coupling piece is obtained in a simple manner, the chamfer or inclined surface indicated enabling the roller drawbar to be easily set aside in a stable manner supporting the said inclined surface and in a well balanced position.
Opfindelsen -forklares i det følgende nærmere i forbindelse med tegningen, der viser et rullestel ifølge opfindelsen, idet 15 fig. 1 er et sidebillede af selve rulleunderstellet, fig. 2 er et plant billede af rulleunderstellet set ovenfra, fig. 3 er et forstørret delsnit gennem rulleunderstellet, fig. 4 er et snit gennem rulletrækstangen, fig. 5 er et frontbillede af rulletrækstangen, delvis i snit, 20 fig. 6 er et sidebillede af rulletrækstangen i standleje, fig. 7 viser skematisk rullestellet inden tilkoblingen af rulletrækstangen, og fig. 8 svarer til fig. 7, men efter tilkoblingen.The invention will be further explained in the following with reference to the drawing, showing a roller frame according to the invention, in which FIG. 1 is a side view of the roller frame itself; FIG. 2 is a top plan view of the roller frame; FIG. 3 is an enlarged partial section through the roller base; FIG. 4 is a section through the roller drawbar; FIG. 5 is a front view of the roller drawbar, partially in section; FIG. 6 is a side view of the roller drawbar in stand position; FIG. 7 is a diagrammatic representation of the roller frame prior to the coupling of the roller drawbar; and FIG. 8 corresponds to FIG. 7, but after the connection.
Som det fremgår af fig. 1 og 2, har rulleunderstellet to 25 tværbjælker 1 og 2, som er indbyrdes forbundet ved hjælp af to par af længdebjælker 3a, 3b og 4a, 4b. Af fig. 2 fremgår det tydeligt, at længdebjælkerne er noget forskudt indefter i forhold til tværbjælkernes ender. Længdebjælkerne i de respektive par er indrettet med lidt afstand fra hin-30 anden og bærer ruller 5, som er drejeligt lejret på aksler 143648 4 6. Længdebjælkerne kan bestå af enkle firkantshulprofiler, som i enderne er sammensvejsede med tværbjælkerne.As shown in FIG. 1 and 2, the roller base has two transverse beams 1 and 2, which are interconnected by two pairs of longitudinal beams 3a, 3b and 4a, 4b. In FIG. 2 clearly shows that the longitudinal beams are somewhat offset in relation to the ends of the lateral beams. The longitudinal beams of the respective pairs are spaced slightly apart from one another and carry rollers 5 pivotally mounted on shafts. The longitudinal beams may consist of simple square hole profiles welded at the ends with the transverse beams.
I fig. 3 vises tværbjælkernes form. De udgøres hovedsageligt af omvendt anbragte U-profiler med et kort og et langt side-5 stykke. Det længere sidestykke 7 er forbundet med længdedra-geme 3 og 4, medens det kortere sidestykke 8 rager ned fra profilbunden 9 overfor sidestykket 7. Ved den frie ende af det længere sidestykke 7 findes en vinkelret mod U-profilet indre fremspringende forlængelse 10. Det kortere sidestykke 10 8 danner en vinkel på mindre end 90°, fortrinsvis 70-80° med bundstykket 9.In FIG. 3, the shape of the cross beams is shown. They are mainly inverted U-profiles with a short and a long side-5 piece. The longer side piece 7 is connected to longitudinal wires 3 and 4, while the shorter side piece 8 protrudes from the profile base 9 opposite the side piece 7. At the free end of the longer side piece 7 there is a perpendicular to the U-profile inner projecting extension 10. The shorter side piece 108 forms an angle of less than 90 °, preferably 70-80 ° with the base piece 9.
Rulletrækstangens opbygning fremgår af fig. 4 og 5. Et akselrør 11 er påmonteret en manøvreløftestang 12 med en længde på 100-200 cm. Akselrøret 11 omslutter en aksel 13, hvis 15 respektive ender er forsynet med en drejelig rulle 14. Akselrøret 11 er desuden forsynet med en akseltap 15, der er således fastgjort, at den danner en ret vinkel med akselen for rullerne 14 og en vinkel på ca. 60° ved manøvreløftestangen 12. Akseltappen 15 kan f.eks. være fastsvejset på 20 trækrøret, idet den fungerer som lejedel for et koblingsstykke 16. Sidstnævnte har et tværsnit, der i hovedsagen er kvadratisk, og det er drejeligt lejret på akseltappen 15. Koblingsstykket 16 har ydermål, der hovedsageligt svarer til det indre tværsnit af tværbjælkerne 1 og 2.The structure of the roll bar is shown in fig. 4 and 5. A shaft tube 11 is mounted on a maneuvering lever 12 having a length of 100-200 cm. The shaft tube 11 encloses a shaft 13, the respective ends of which are provided with a rotatable roller 14. The shaft tube 11 is furthermore provided with a shaft pin 15 which is fixed to form a right angle with the shaft for the rollers 14 and an angle of approx. . 60 ° at the maneuvering lever 12. The shaft pin 15 can e.g. be welded to the 20 drawbar, acting as a bearing member for a coupling piece 16. The latter has a cross-section which is generally square, and it is pivotally mounted on the shaft pin 15. The coupling piece 16 has outer dimensions which correspond substantially to the inner cross-section of the beams. 1 and 2.
25 Den øvre kant af koblingsstykket 16, som vender imod manøvreløftestangen 12, er affaset og udformet med et spor 17. Dette spor ligger på tværs af forlængelsen af koblingsstykkets omdrejningsakse. Sporet 17 er indrettet til at optage den kortere sidedel 8 af tværbjælkerne 1,2 (se nedenfor).The upper edge of the coupling piece 16, which faces the maneuvering lever 12, is bevelled and formed with a groove 17. This groove lies transversely of the extension of the rotary axis of the coupling piece. The groove 17 is arranged to accommodate the shorter side portion 8 of the transverse beams 1,2 (see below).
30 Den diametralt modsat liggende kant af koblingsstykket 16, dvs. den underste kant, som er bortvendt fra manøvrestangen 12, er på samme måde affaset til dannelse af en støtteflade 18. Denne flade ligger i et tangentialt niveau T (fig. 4) med rulletrækstangens ruller 14. Formålet med affasningen 5 143648 eller støttefladen 18 fremgår tydeligt af fig. 6. Når rulletrækstangen er stillet væk, understøttes den af affasningen 10 og står derfor stabilt.The diametrically opposite edge of the coupling piece 16, ie. the lower edge facing away from the maneuvering rod 12 is similarly bevelled to form a support surface 18. This face lies in a tangential level T (Fig. 4) with the rollers of the roller drawbar 14. The purpose of the bevel 5 or support surface 18 is stated. clearly shown in FIG. 6. When the roller bar is set, it is supported by the bevel 10 and is therefore stable.
I fig. 7 ses et rulleunderstel, som med sine ruller 5 hviler 5 på gulvet 9, og som skal anbringes et andet sted. Til dette formål anbringes rulletrækstangen under en af tværbjælkerne, som vist. Herved indtager rulletrækstangen en stilling, der svarer til stillingen ifølge fig. 6, dvs. i hvilestilling.In FIG. 7, there is shown a roller frame which, with its rollers 5, rests on the floor 9 and which must be placed elsewhere. For this purpose, the roller drawbar is placed under one of the crossbars, as shown. Hereby, the roller drawbar occupies a position corresponding to the position of FIG. 6, i.e. in a resting position.
Det ses således, at rulletrækstangens manøvreløftestang 12 10 i denne stilling indtager en i hovedsagen vertikal stilling, således at lastning af rulleunderstellet ikke forhindres.Thus, it is seen that in this position the maneuvering lever 12 10 of the roller drawbar occupies a substantially vertical position so that loading of the roller chassis is not prevented.
Den kortere skråtstillede sidedel 8 på U-profilet befinder sig direkte over sporet 17 i koblingsstykket 16. Manøvreløftestangen 12 svinges nu i retning af pilen P indtil den i 15 fig. 8 viste stilling opnås. Det fremgår tydeligt, hvorledes koblingsstykket 16 indgriber i U-profilets indre, specielt hvordan den korte sidedel 8 er indført i sporet 17 og ved sin skråstilling er delvis selvspærrende forankret heri.The shorter inclined side portion 8 of the U-profile is directly above the groove 17 in the coupling piece 16. The maneuvering lever 12 is now pivoted in the direction of the arrow P until it is shown in FIG. 8 is achieved. It is clear how the coupling piece 16 engages in the interior of the U-profile, especially how the short side part 8 is inserted in the groove 17 and at its inclined position is partially self-locking anchored therein.
Når stillingen ifølge fig. 8 er opnået, kan et rulleunderstel 20 manøvreres uden vanskeligheder. Ved den svingbare lejring af koblingsstykket 16 muliggøres passage af meget skarpe kurver, hvilket gør rulleunderstellet let manøvrerbart på lille plads.When the position of FIG. 8 is achieved, a roller chassis 20 can be operated without difficulty. The pivotable bearing of the coupling piece 16 allows for the passage of very sharp curves, which makes the roller chassis easily maneuverable in a small space.
En afglidnlng af rulleunderstellet fra rulletrækstangen er udelukket, da udformningen af sporet 17 med dettes affasede 25 sidevægge fastholder den tilsvarende skråtstillede sidedel på U-profilet 1, hårdere, jo større trækkraften er på rullestangen. Ved det valgte vægtstangsforhold opnås, at det på koblingsstykket i vertikal retning påførte tryk, der i et drejningsmoment overføres til akslen 13 for rullerne 14, kom-30 penseres af det drejningsmoment, som udøves på akslen 13, af egenvægten af manøvreløftestangen 12. På den frie ende af manøvreløftestangen 12 kan et ikke vist håndtag indrettes og forsynes med en vægt til yderligere kompensation af det drejningsmoment, som udøves af det lastede rulleunderstel.A slip of the roller chassis from the roller draw bar is excluded as the design of the groove 17 with its beveled 25 side walls retains the corresponding inclined side portion of the U-profile 1, the harder the greater the traction on the roller bar. At the selected lever ratio, the pressure applied to the coupling piece in a vertical direction transmitted in a torque to the shaft 13 of the rollers 14 is offset by the torque exerted on the shaft 13 by the intrinsic weight of the maneuvering lever 12. at the free end of the maneuvering lever 12, a handle not shown may be arranged and provided with a weight for further compensation of the torque exerted by the loaded roller frame.
